Answer:
f(x)=x^2+3
f(x+y)=(x+y)^2+3
this is done by replacing x with (x+y)
f(x+y)=x^2+2xy+y^2+3
therefore : f(x+y)= x^2+y^2+2xy+3

<span>1 ft =(1/5280) mi </span>
<span>3/10 in=3/10*(1/12)*(1/5280) mi </span>
As the word suggests, a quarter-sphere is a quarter of a sphere, and thus the volume of a quarter-sphere is a quarter of the volume of the sphere.
The volume of a sphere is computed as

So, the volume of a quarter-sphere is

The <em>correct answer</em> is:
It does not.
Explanation:
The scale of a graph just tells us how many units are between numbers. This does not change the overall distance represented.
For example, I can have two graphs on which the x-axis goes to 60. On one graph, I can count by 10s for my scale, while the other graph uses 5s. While the scales are different, the same distance is represented.
Hello! For these types of inequalities, we put what’s in the middle to solve for the one behind and ahead. -3x + 12 is in the middle. Let’s solve it like this: x + 4 < -3x + 12. Add 3x to both sides to get 4x + 4 < 12. Subtract 4 from both sides to get 4x < 8. Divide each side by 4 to isolate the “x”. 8/4 is 2. x < 2. Now, let’s solve the other like this: -3x + 12 < 24. Subtract 12 from both sides to get -3x < 12. Divide each side by -3 to isolate the “x”. 12/-3 is -4. Because you divided by a negative, you flip the sign over into greater than. The solution to the compound inequality is -4 < x < 2, but none of the choices show that. In this case, the part of the solution is x < 2, so if you had to pick from one of the answers, the answer is C.
